Bohr Model of the Hydrogen atom.

Question

Frequency of the series limit of Balmer series of hydrogen atom interms of Rydlberg constant R and velocity of light c is

Moderate

A

RC
B

4RC
C

4/RC
D

RC/4

Solution

$E = {RchZ}^{2} (\frac{1}{{n_{1}}^{2}} - \frac{1}{{n_{2}}^{2}}) ∴ hv = {Rchz}^{2} (\frac{1}{{n_{1}}^{2}} - \frac{1}{{n_{2}}^{2}}) ∴ v = Rc {(1)}^{2} (\frac{1}{4})$
